Purl 3 Together (p3tog)

The p3tog, or purl 3 together, is a double decrease that leans to the right when viewed from the opposite side of the work. It takes three stitches and turns them into a single stitch that slants toward the right and is often used on wrong-side rows.

To work it, insert your right-hand needle into the first three stitches on the left-hand needle at the same time, just like you would to purl a single stitch. Catch the working yarn with the tip of the right-hand needle and draw this new stitch through all three of the stitches on the left-hand needle. Finally, slide those three stitches off the needle.

The following video demonstrates how to work a p3tog:
